Meyer Lemon trees are great additions to gardens or indoor spaces. You might enjoy using their fruit or the smell of their blossoms, which are white with a hint of purple at the base. The plants have a long history as ornamental house plants. They were originally bred by mixing lemon and mandarin plants. This mix gives the fruit its eye-catching, golden color and size. Meyer Lemons, in particular, bloom all year round, perfuming the air with their sweetness.
